Y., A CORFORATION OI DELAWARE ABSORBER FOR anrnmaaaroas I Application filed Kay 7, 1930. Serial No. 450,416.

This invention relates to an improvement in the art of refrigeration and more particularly to an absorber or evaporator for use in a refrigerator of the absorption type wherein one or more devices are employed for effecting contact between a liquid and'a gas, and it is an object of the invention to increase the efliciency of a refrigerator of this character by increasing the amount of surface upon which the liquid is exposed without increasing the resistance to the circulation of gas.

In said drawing:

Fig. 1 is a fragmentary section taken on the line 1-1- of Fig. 2 of an absorber or evaporator illustrating one application of the invention;

Fig. 2 is a horizontal section through the absorber showing a top plan view of one of the disks; and

Fig. 3 is a section on the line 33 of Fig. 2.

Referring to said drawing in which the I same reference numerals are used to denote corresponding parts throughout the several views, 10 indicates the shell of an absorber or evaporator of general cylindrical formation and of ordinary steel construction. In the outer shell 10 are mounted a series of plates or disks 11 having upturned flanges 12 at their outer edges disposed at right angles,

' the passage of gas, the edges of the openings being struck upwardly or elevated to provide elevatedrims or flanges 15 and 16 respectively to prevent liquid from pouring therethrough. These rims serve as retaining walls or dams for "reservoirs or pools of liq uid refrigerant spread over the surface of the disks causing such liquid to spread in a ribs 18 and 19 which extend inwardly from the flange on opposite sidesof the disk in substantially overlapping relation and require liquid to travel in a circuitous or tortuous path from the point where it drops or is deposited upon the disk to the discharge passage 17. The rib 19 has its inner end terminating in the rim 15 of the aperture 13 as shown.

The disks are arranged withthe openings therein staggered or out of alinement so that the passagev 17 will overlie the impe'rforate' side of the next'lower disk. By noting Fig. 2 it will be apparent that liquid dropping upon the disk on the imperforate side of the same will be required to travel between the ribs 18 and 19, then between the flan e 12 at the pe riphery of the disk and the rim of the open-- ing 13, then around to the discharge passage 17 where it may pass to the underside of the disk and spread thereover to certain extent, additional accumulation however causing the liquid to drop directly from the discharge passage onto the next lower disk. The arrangement of the disks with their openings out of alinement will cause a zig-zag flow of gas upwardly through the absorber and a corresponding downwardly flow of liquid.- This will effect a thorough exposure of one to the other and insuring a proper cominingling of the two.

While I have described an absorber or evaporator, my invention contemplates the use of the disks in any capacity where it is desired to insure a thorough contact of a gas and liquid and I therefore do not desire to be limited by what is shown in the drawings and described in the Specification, but only as indicated in the appended claims.

I claim:

1. An absorber element for use in a gas and liquid contact apparatus for effecting a thorough commingling of the gas and liquid comprising a plate having ribs on its upper surface along its central portion in overlapping re1ation,-'said plate having openings with raised rims at one side of said ribs and an imperforate portion at the opposite side of said ribs, the rim of one of the openings being cut through to provide a discharge passage whereby liquid deposited upon the plate on the side remote from the discharge openings will be required to travel over the 7 plate in a circuitous path between said ribs to said discharge opening.

2. Aplate for use in a gas and liquid contact apparatus for efiectinga thorough commingling of the gas and quid comprising a perforated plate having an opening for the passage of liquid and gas therethrough, a raised rim about said opening for restricting the flow of liquid from the plate, raised ribs I 1 extending from opposite edges of the plate -in liquid from overlapping relation, one of said ribs being connected to said rim, said rim being cut through to provide a passage for the discharge of liquid from the plate, said ribs and rimmed opening being arranged to direct liquid in a circuitous path over the surface of the from.

3. An absorber element comprising a plate stamped to provide a plurality of openings therethrough, the plate and openings being provided with raised rims, the rim about one of the openings being cut through to provide a discharge passage through said openin from the surface ofthe plate, and a raised ri connecting a continuous rim about one of the o enin s and the rim of the plate at a remote e ge o the same.

4. An absorber element comprising a ressed metal plate having a air of openmgs for the passa e of gas an liquid therethrough, the meta around said openings being struck u providing a rim to revent owing directly from t e surface of-the plate throu h sald openings, and a raised rib extending rom one of the openings to the rim of the plate at the remote edge of the plate.

In testimony whereof I aflix m si ature.

ALVAR N plate before it is discharged there-
